I would like this very much.  I'd be happy to give you feedback on it if you
choose to work on one.

I've gotten it and modified the shebang line to load python2.1, the
mixer.Sound line to load a wav I have available, and the mixer.init to reflect
the sample rate of the wav file: mixer.init(44100, 16, 0)

When I run echo.py I get the following output:
$ ./echo.py
(44100, -16, 1)
SHAPE1: (88160, 2)
Traceback (most recent call last):
  File "./echo.py", line 25, in ?
    myarr[:length] = a1
ValueError: Object too deep for desired array

Am I doing something wrong here?

I'm running Debian Unstable, so I *think* running python 2.1 (with Numeric
2.1) is as easy as invoking the scripts with: #!/usr/bin/python2.1.  If I'm
being dense, I'd be happy to be told.

Thanks for the quick response; sorry to draw the conversation out.  I haven't
had time to play with the code until just now.
